DECARBONIZER FOR-"ENGINES:

Application filed April 2, 1918. Serial No. 226,233.

To all whom it may concern.

Be it known that I, FRED 0-. STEKELBERG, a citizen of the United States, residing at Middleton, in the county of Daneand' State of Visconsin, have invented new and useful Improvements in Decarbonizers for Engines, of which the following is a specification.

This invention relates to internal combustion engines, of vehicles particularly to accessories therefor, and has for its object the provision of means whereby kerosene will be automatically supplied to the carbureter through its air inlet whereby the kerosene will be vaporized and mixed with the gasolene vapor for preventing formation of carbon within the cylinders of the engine.

An important object is the provision of a device, of this character which may be placed upon any convenient location within the motor vehicle and which will automatically supply kerosene in the form of a fog or drops into the air inlet of the carbureter as long as the engine is running and the device is agitated by the travel of the vehicle, the feed being controlled entirely by the suction produced by the engine pistons.

Another object isthe provision of a device of this character which will be extremely simple and inexpensive in manufacture and installation, which will be highly efficient in preventing carbonization and removing carbonization within an engine, and which will consequently save gasolene whileincreasing the smooth and easy running of the engine.

With these and other objects and advantages in view together with a general improvement of the art, the invention consists in the novel construction and arrangement to be hereinafter more fully described and claimed as illustrated in the accompanying drawings in which Figure l is a sectional view through the forward portion of an automobile showing my device applied thereto and Fig. 2 is a longitudinal sectional View through my device.

Referring more particularly to the drawing the letter A designates the forward portion of a motor vehicle, E the engine, C the carbureter provided with an air inlet eye and D represents the dash.

In carrying out my invention I provide a cylindrical receptacle 5 secured upon the dash D by means of suitable brackets 6 at Specification of Letters Patent.

any suitable location. The top and bottom heads 7 and '8 of' the cylindrical casing 5 are closed and the top head is provided with a suitable opening-9 through which the receptacle may be filled with kerosene, the opening 9 being c-losedbya plug 1O. A suit able gage 11 isproperly disposed upon the side of the receptacle 5 for indicating the depth of kerosene withinthe receptacle. The top head 7 is provided centrally with an opening 11 Within which is threaded a suitable packing nipple 12 through which extends a pipe or tube 13 which terminates within the upper portion of the receptacle 5 and which has its other end extended downwardly and disposed withinthe air inlet 1' of the carbureter C.

As long-as the engine is running and the tank is agitated, as during the travel of the vehicle, the action of the pistons will create suction at the air inlet I and suction will be consequently produced throughout the pipe 13 which will result in drawing kerosene from the receptacle 5 through the pipe 13 and into the carbureter G. As soon as the kerosene enters the carbureter C it will of course be mixed and vaporized with the gasolene vapor and will be supplied to the engine. It will of course be understood that the kerosene will not pass from the receptacle 5 into the carbureter in the form of a steady stream but will pass thereto more in the nature of a spray for the reason that the kerosene within the receptacle 5 will constantly be agitated by the jarring of the vehicle and will be consequently splashed against the end of the tube 13 into which it will be drawn by suction as previously described. It will of course be apparentthat the amount of kerosene passing into the tube 13 at each revolution of the engine will be comparatively small but it will be also apparent that this action will be continuous as long as the engine is running. It is well known that the introduction of kerosene into the cylinders of an engine prevents the formation of carbon therein and helps to remove carbon which has already been formed.

From the foregoing description and a study of the drawing it will therefore be apparent that I have provided novel means whereby kerosene may be introduced into the air inlet ofa carbureter automatically as long as the engine is running and the vehicle is traveling whereby the formation of carbon will be prevented and whereby the engine will be caused to run more smoothly with a less expenditure of gasolene.

It will of course be understood that I reserve the right to make such changes in the form, proportion and arrangement of parts as will not depart from the spirit of the invention nor the scope of the subjoined claims. I

Having thus described my invention I claim 1. In combination with the air inlet of a carbureter, a receptacle, and a tube extending into the top of said receptacle and'having its other end extending into the air inlet of the carbureter whereby the suction at said air inlet will cause kerosene within said receptacle to be drawn in the form of a fog through said tube intothe carbureter when said receptacle is agitated.

2. An attachment for internal combustion engines, comprising a receptacle, and a tube extending into the top of said receptacle and terminating within the upper portion thereof, the other end of said tube extending into the air inlet of the carbureter of the engine whereby the suction at such air inlet will cause kerosene within said receptacle to be drawn in the form of drops through said tube into the carbureter when said receptacle is agitated.

In testimony whereof I afiix my signature.

FRED C. STEKELBERG.
